Miami, Oct 13 (EFE).– The shark migrations that occur at this time of year on the southeastern coast of the United States set off a new alarm at Miami Beach, where at least a hundred were spotted.

The school of sharks, swimming in a southerly direction Monday in search of warmer waters, was just 50 meters (160 feet) from the shore at Miami Beach, according to videos screened by local television channels.

Tourists also posted their eyewitness reports on social networks about the migration of sharks, predators of the blacktip reef shark species that generally feed on fish, though occasionally they attack bathers.

While no attack was reported, experts advised beachgoers to stay alert and do nothing to bother the sharks when they are close to shore.

“It’s very important for people who visit Florida waters to be aware of their surroundings, understand the relative risks, and be educated on various shark issues such as behavior,” said scientist Brent Winner of Florida Fish and Wildlife Conservation on Channel 10.

According to the expert, shark activity is particularly intense between April and October in Florida waters, as they move north in the spring and summer, and close to shore as they head south in the fall and winter.

On some occasions, such as in 2013, the shark migration forced some beaches on the southeast Florida coast to be closed.

So far this year there have been 16 known shark attacks in Florida, though they have taken no lives, according to the International Shark Attack File. EFE
